TO ALL WHOM IT MAY CONGERNz' Y Be n known that I, JOHN EDWIN am, eine any of chicago, in uw @may of cook, misma of, run4 nois, have invented Vcertain new and useful Improvements in Boring-Machine for Boring Earth; and I do hereby declare thatthe followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- I v Figure 1 represents a topor plan view, v v Figure 2 a side view, with part of the upper framework cutaway, Figure 3 a vertical section of bevelwheel, showing the bearings, and Figure 4 an end view of the bit or borer. l Like letters refer to the same parts in all ofthe iigurcs.

The nature of my invention consists in providing an'earth-boring` machine with a hollow bit or-augershaft, to overcome or avoid `the great suction found in withdrawing. the auger loaded with earth; in making the point ofthe auger ofaseparate rod orbar; `in-a novel mode of withdrawing the auger; in locating and attaching the gearing and auger to a rock-shaft or beam; in providing the machine with a. device for settling theauger; in providing the gear-wheel, by which the shat'tof the auger is ,supportedand operated,` with a colla-rvtive position of any of the operative parts.

bearing, and in the several combinations hereinafter setvforth and claimed. l

To enable othcrsskilled-in the art to make and use myinventon, I will proceed to describe the construction and operation of my machine.

The frame A, for a. size suitable for boring holes for fence-posts,'is. made of three by two and one-half timbersrfour feet and six inches high, two feet square at the top, and two by three feet at the bottom; Other sizes and dimensions can be used, however. i In the4 middlecot this frame, at the top, Iattach a rocking-beam, K, by means of' bcxesior bearings, m. To this beam, K, are attached all of the parts'w-hich -operate in boring, so that the position of 'the auger can be varied toward either 'of the inclined sides, without changing the rela- Oneadvantage of this arrangement of the-parts on a rock'ing-beamfis, that the auger-can be thrown to vone side of the'machine, and then, by canting thc machine, holes cansbe bored'by the side ot'` an old fence without removing any portion of the fence. j

.On the middle of this' beam K,Imake a hole about` three and one-halfinches in diameter, and insert therein a'rcollar or beal'ing,j, (15g. 3,) for the bevel-wheel G. The wheelG is about eleveii inches in diameter, and, so far as the coge` are concerned, is of the usual construction; Its centre is somewhat raised, and a square mortise is made through it. To the under surfnceI cast a hollowor cylindrical projection, z', the hollow being somewhat larger than the square mortise above it,- and its outer surfaceor periphery ts the inside of the .collar or bearingj, so that, by means of this projection z', the wheel is kept in place by and rotates upon the collar j. The wheel Gis operated by the corresponding gear-wheel E, whiclris 4 about seven inches in diameter, and is attached to the shaft E, which is rotated'by the'crank shown, when used for boring post-holesQa-nd by a pulley when used for boring wells. Y,

The shaft E is supported in and by the elevated journal-boxes or bearings J and J,which 'are also fastenedrto the rocking-beam. To'the rocking-beam I also attach,or insert into it. a vertical 4rod or post, I, which extends upwards the height it is designed'to more the auger, and its oce is to guide .the bar I-I and keep it in place.l It passes through a slot in bar II, so that there will notbc any binding, whatever the position ot' H may he.

I make my auger in two parts orr sections", and either Vscrew or weld them together. The upper section B is right-angled or square, and fits the mortse-in wheel G. The lower seption B is circular and hollow. I make it usually ot' inch and one-quarter gaspipe. Near the upper end bf this sectionLIvmakc a side slot, b, and at the lower end I make the hollow square, just enough to prevent the point from turning in the shaft, and at 'theA extreme lower end of this shaft I attach, by a screw, the bits or cutters e. I then insert into the hollow por. tion B a rod, which is enlarged at its lower end, d, and forms the auger-point. It is provided with a square shoulder, c, which lits the square opening in the end of the shaft, so as to make the point turn with the auger. The upper end of thc rod, to which the point d is attached, is brought out through the slot b at a, and is kept out by placing a piece of iron under it, or by running a small bolt through theshaft lbehind it, and is thereby prevented from falling' out, while the point is allowed to fall sutliciently low, when drawn out, to permit a4 current of air to pass through the hollow section, 'and prevent the usual suction when lifting the earth upon the auger out of-the hole, so that one person Vcan lift the-auger with the earth easily.

In order to prevent the beam K from turning so asto bind on the shaft, and the wheels upon each other, and also to hold thc auger iu position, to the under side of the beam I attach a spring or bar, L, which extends downA to the lower cross-'bar of the frarne M, wheret is held in place by the pin NQmhich is passed through one of a series of holes in thebar m, and through avslot in the spring or lever L.

When the auger hasheen bored into the earth, it is elevated by means of the crankshaft D, which has a rope or chain, h, woun d upon it. At the lower end of the rope h, I attach a grapple, N,'whch goes under the collar or projection n of the shaft of the auger. In wells where such ring or projection would be in the way, the grapple is made to clamp directly upon the/shaft. Usually the bitof Vthe auger will draw it into the earth suiliciently, but in sand it will not, so that to enable me to force it in, I pivot to the top of the auger-shaft a, bar, H, which is slotted atonellend, and the rod or post I passes through such slot. At the other endl attach the cord, rope, or chain g, which winds upon the shaft C, and forces the auger down. fl'ts operation will be found detailed inthe description:

Having thus` fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The bar H, in combination with the rod or post I, rope g, and shaft C, when constructed and operating substantially as and for the purposes specitied. l

2. The combination and 'arrangement of the gear-wheels F and G, shaft E, and' lever L, with the rockingbeam K, substantially as specied.
